However others are less pessimistic and it has even been claimed that the mysterious ?Wow! signal? received in 1977 originated from the direction M55.б  Sadly, this still unexplained pulse of radio energy originated from a location rather to the northwest of M55 so I doubt if the source was this cluster (if indeed the signal was genuinely of extraterrestrial origin). ...

... Bad Astronomy . ... Mad Science . ... I was wondering why scientists think that a black hole can form wormholes or gateways to alternate universes. ... When thinking about Einsteinien gravity and how gravity affects space-time on a 2-dimensional plane, I figured that if you viewed the Universe as a balloon (a balloon for the explanation of everything moving away from eachother at the same time), then the black hole would basically be doing the same thing as when you push your finger into a balloon. ...

. Mars has become the center of intense interest since the Martian Meteorite results were announced. Currently there is a lively debate whether or not primitive life formed there or not.

How the rings were formed. ... Because of the velocity of mutual collisions increases at the approaching to the planet, there is a region near an every planet where the particles reaching the definite sizes begin to pull due to the mutual collisions. ... Any big particle passes the whole cycle from the destruction to the restoration. ... Why the rings are so flat? ... The gravitation compresses the system from all sides and the rotation axis, but it cannot prevent compression along the axis. ...
